Build a Real-World GraphQL API with HotChocolate & .NET 10

Are you tired of building the same old CRUD APIs that every tutorial teaches? Do you want to learn GraphQL the right way — by building something real that you can actually put on your resume?

This course takes you beyond the basics. You will build a complete Job Board API — similar to LinkedIn or Indeed — using HotChocolate, the most powerful GraphQL library for .NET, and the latest .NET 10.

This is not a toy project. By the end of this course, you will have a production-ready API with real features that companies actually use — authentication, real-time notifications, advanced filtering, pagination, and cloud deployment.

Why GraphQL over REST?

• Fetch exactly the data you need — no over-fetching or under-fetching

• One endpoint for all operations — cleaner and more flexible than REST

• Built-in real-time support with Subscriptions — no extra setup needed

• Self-documenting API — your schema IS the documentation

Why HotChocolate?

• The most popular and powerful GraphQL library for .NET developers

• Built-in support for Filtering, Sorting, and Pagination — out of the box

• Seamless integration with Entity Framework Core and .NET ecosystem

• Used by companies worldwide in production applications

What you will build — Job Board API

Throughout this course, you will build a real Job Board API step by step. Here is what the final project includes:

• Companies can post jobs, update them, and delete them

• Applicants can browse jobs, filter by salary and location, and apply

• Real-time notifications when a new job is posted using Subscriptions

• JWT Authentication with Refresh Tokens — secure and production-ready

• Advanced filtering, sorting, and cursor-based pagination— the right way

• Clean Architecture — 4-layer project structure used in real companies

• Azure Deployment — your API live on the internet

This course is different because

• You build ONE real project from start to finish — not isolated disconnected examples
